By default, a typical WordPress blog will display the very first comment at the top of the comments template. While I prefer this way, many others do not. If you are someone that would like your WordPress blog to display the most recent comment on top, Moses of WPThemesPlugin.com explains how to display recent comments on top.
Unlike most of the WordPress hacks we’ve covered here at Hack WordPress, this one is not something that can be controlled from within the WordPress theme. You’ll have to actually go into the comment-template.php file (in the wp-includes folder) in order to make this adjustment. The good news is that it is REALLY easy.
